Proposal for an OFDM-based 802.16 BWA Air Interface Physical Layer

A Physical Layer based on OFDM modulation with parameters similar to 802.11a, HIPERLAN/2 and MMAC is presented. The PHY covers data rates of 6.7 to 60 Mbit/s with 20 MHz channel spacing. The OFDM based PHY exhibits, in addition to good link budget, excellent multipath robustness. Aligning the BWA PHY with a contemporary high-speed wireless LAN PHY standard will result in widely available, cost effective and high-performance solution. Purpose To present a proposal which will serve as a baseline of the BWA PHY layer. Notice This document has been prepared to assist the IEEE 802.16.
